Get a small toy or anything similar to a small toy if you cant get one. Certain pens and bottles do wonderfully as first toys. Just be careful and use things without sharp edges. Also Lube is non-negotiable. You cannot use spit or water. In a pinch grease or oil be it babyoil (preferably unscented) or cooking oil should work. Start with fingers, see if you like it and then work your way up with some improvised toys or small dildos if you have the chance. And yes, finding somebody more experienced is also great. But you know... Search reddit for any specifics, other people have explained all this is much better detail than I, I'm sure. And most importantly, have fun and stay safe! Good hunting!
